how to solve this question please do solve with soln​

Answer 1

Answer:

2

Step-by-step explanation:

$\frac{ {a}^{2} }{2b} - \frac{ {a}^{2} }{4b} \\ = \frac{( {a}^{2})(4b) - ({a}^{2})(2b) }{(2b)(4b)} \\ \frac{4 {a}^{2}b - 2 {a}^{2}b }{8 {b}^{2} } \\ \frac{2 {a}^{2}b }{8 {b}^{2} } \\ \frac{ {a}^{2} }{4} \\ = > {a}^{2} = 4 \\ = > a = \sqrt{4} = 2$

Take LCM of the denominator.

then solve
